Environmental heterogeneity promotes spatial resilience of phototrophic biofilms in streambeds

Andrea Rinaldo, Tom Ian Battin, Hannes Markus Peter, Enrico Bertuzzo, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez

The loss of environmental heterogeneity threatens biodiversity and ecosystem functioning. It is therefore important to understand the relationship between environmental heterogeneity and spatial resilience as the capacity of ecological communities embedded ...

Experimental evidence for strong stabilizing forces at high functional diversity of aquatic microbial communities

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Florian Altermatt

Unveiling the mechanisms that promote coexistence in biological communities is a fundamental problem in ecology. Stable coexistence of many species is commonly observed in natural communities. Most of these natural communities, however, are composed of spe ...

Metapopulation persistence and species spread in river networks

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

River networks define ecological corridors characterised by unidirectional streamflow, which may impose downstream drift to aquatic organisms or affect their movement. Animals and plants manage to persist in riverine ecosystems, though, which in fact harbo ...

Spatial effects on species persistence and implications for biodiversity

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis, Amos Maritan

Natural ecosystems are characterized by striking diversity of form and functions and yet exhibit deep symmetries emerging across scales of space, time, and organizational complexity. Species-area relationships and species-abundance distributions are exampl ...

Predicting spacial similarity of freshwater fish biodiversity

Andrea Rinaldo, Mihaela Marian

A major issue in modern ecology is to understand how ecological complexity at broad scales is regulated by mechanisms operating at the organismic level. What specific underlying processes are essential for a macroecological pattern to emerge? Here, we anal ...

On biodiversity in river networks: A trade-off metapopulation model and comparative analysis

Andrea Rinaldo

A discrete, structured metapopulation model is coupled with the strictly hierarchical competition-colonization trade-off model, in which competitively superior species have lower fecundity rates and thus lower colonizing ability, to study the resulting bio ...

Molecular analysis of the biodiversity of protists in hydrocarbon-polluted and pristine soils

Enrique Lara

Eukaryotic microorganisms are an essential component of the Earth's global diversity. It is believed that the number of protistan taxa far outnumbers the one of viruses and bacteria. The taxonomic classification of these organisms, which also represent the ...
